TNE Korea returned to an operating profit in the first half of 2026 on volume production of air blowers for hydrogen and SOFC power generation, and its shares gave back much of their intraday surge on the first trading day.
For 2025, consolidated revenue was KRW 23.448 billion, with an operating loss of KRW 1.807 billion and a net loss of KRW 6.953 billion.
In the first half of 2026 the company swung to an operating profit of KRW 3.46 billion on revenue of KRW 21.11 billion, and revenue rose 180% year on year.
Air blowers for hydrogen power generation made up 36.1% of first-half 2026 revenue, and hydrogen-related products together made up 45.7%.
In the IPO, the institutional book-building ratio was 1041.02 to 1 and the retail subscription ratio was 1253.39 to 1.
The first-day intraday high was KRW 34,500, or 125.49% above the offer price. As of 18:14 KST the price was KRW 21,050, which is 37.58% above the offer price.
TNE Korea is a high-speed turbomachinery maker that was founded in 2014 and develops and produces high-speed turbo machinery systems. Its headquarters is in Osong-eup, Heungdeok-gu, Cheongju, Chungbuk. The company name is built from the initials of the words Turbo and Energy.
Its core technologies are oil-free bearings, high-speed turbo technology and power electronics. Its products span turbo blowers for water treatment and industrial sites, air blowers for hydrogen fuel cell power generation, and air compressors for hydrogen vehicles.
In the first half of 2026, air blowers for hydrogen power generation generated KRW 7.616 billion, or 36.1% of revenue, and hydrogen-related products accounted for 45.7%. The company co-developed the power-generation air blower with a US SOFC maker, signed a supply contract and began full-scale mass production in 2026.
According to THE ELEC, revenue from SOFC air blowers grew from KRW 0.5 billion in 2023 to KRW 2.0 billion in 2024 and KRW 8.7 billion in 2025. The company plans to extend its products to semiconductor processes and aerospace.
We do not describe market share or price comparisons against competitors, because no verified public data was found.
According to reported consolidated results, 2025 revenue was KRW 23.448 billion, with an operating loss of KRW 1.807 billion and a net loss of KRW 6.953 billion. The company also posted an operating loss of KRW 1.6 billion in 2024, so 2025 was a second straight year of operating losses.
In the first half of 2026 it turned profitable, with revenue of KRW 21.11 billion and operating profit of KRW 3.46 billion. First-half revenue rose 180% from a year earlier. The IPO used the technology special listing route. The offer price was set at KRW 15,300, the top of the target range.
The deal covered 2.4 million shares and raised KRW 36.72 billion. The market capitalization at the offer price was KRW 173.7 billion. On the first trading day, October 29, 2026, the shares climbed as high as KRW 34,500 intraday. Afterward, gains narrowed in the afternoon, and the stock traded at KRW 21,600 at 14:08.
As of 18:14 KST the price was KRW 21,050, market capitalization was KRW 238.9 billion and trading value was KRW 448.1 billion. The exchange noted that the volatility interruption mechanism was not applied on the first trading day.
The company expects revenue of KRW 55.2 billion in 2026 and KRW 96.6 billion in 2027. First-half 2026 revenue was KRW 21.11 billion, so meeting the 2026 target implies roughly KRW 34.1 billion in the second half.
Korea Investment & Securities, citing the company's entry into the supply chain of US-based Bloom Energy, estimated 2027 revenue of KRW 108.0 billion and operating profit of KRW 21.4 billion.
The same report said revenue estimates could be revised up if the on-site power market grows faster and the company's penetration of the value chain rises. As demand context, it was reported that Bloom Energy raised its 2026 revenue target to a range of USD 3.4 billion to 3.8 billion.
The IPO proceeds are earmarked for plant expansion, production automation, additional production staff and next-generation product R&D. They also include repayment of borrowings.
The key operating checkpoints are whether capacity additions keep pace with revenue growth and whether the operating margin holds near first-half levels.
Revenue from SOFC air blowers grew from KRW 0.5 billion in 2023 to KRW 8.7 billion in 2025. The company signed a supply contract with a US SOFC maker and began mass production in 2026. It is extending into SOFC-based power generation to address rising power demand from AI data centers. The bulls argue that entering volume production could lift the product's revenue contribution further.
The company moved from an operating loss of KRW 1.8 billion in 2025 to an operating profit of KRW 3.46 billion in the first half of 2026. First-half revenue rose 180% year on year. One reading is that rapid revenue growth spread fixed costs over a larger base. That reading rests on a single half-year of results.
A total of 2,274 institutions joined the book-building, and 99.87% of participants bid at or above the top of the price band. The retail offering drew subscription deposits of about KRW 5.75 trillion. The IPO raised KRW 36.72 billion.
The proceeds go to expansion, R&D and debt repayment, which can support growth investment and ease the financial burden.
The company posted operating losses in 2024 and 2025, and its first operating profit came in the first half of 2026. Its 2025 net loss of KRW 6.953 billion was far larger than the operating loss. We do not assert why the net loss exceeded the operating loss, because the available data is limited. Whether the half-year profit carries through a full year has not yet been confirmed.
Air blowers for hydrogen power generation made up 36.1% of first-half 2026 revenue, and hydrogen-related products accounted for 45.7%. The product was co-developed and contracted with a single US SOFC maker, according to reports. Revenue shares by customer were not confirmed. Even so, demand shifts at one customer or in one market could weigh heavily on results.
The company's targets are revenue of KRW 55.2 billion in 2026 and KRW 96.6 billion in 2027. Against 2025 revenue of KRW 23.448 billion, the 2027 target assumes very large growth. The IPO used the technology special listing route, so delivery against projected results is an important point of scrutiny. A shortfall could change how the market assesses the company.
The growth case rests on rising power demand from AI data centers and the expansion of on-site power generation. If that investment slows or the US policy and trade environment changes, orders from SOFC makers could shift.
Exchange rates and interest rates also affect the profitability and capital spending of an export-oriented manufacturer. The company's exact export share and currency sensitivity were not confirmed.
Higher output depends on capacity additions, automation and hiring. The IPO proceeds are also intended for plant expansion, production automation and additional production staff. Delays in expansion or yield problems could strain delivery schedules and costs. The newer target fields of semiconductor processes and aerospace have no confirmed revenue contribution yet.
Price swings are wide right after a listing. The first-day intraday high was KRW 34,500. At 14:08 the stock traded at KRW 21,600. The exchange noted that the volatility interruption mechanism does not operate on the first trading day. We could not confirm the structure of freely tradable shares or the lock-up release schedule.
TNE Korea began with turbo blowers for water treatment and is shifting its revenue mix toward air blowers for hydrogen and SOFC power generation. The move from an operating loss and net loss in 2025 to an operating profit in the first half of 2026 is a clear change in operating metrics.
The bulls point to expanding mass production, funding for capacity additions and brokerage estimates. The bears point to the short profit record, concentration in a single product and customer, and the uncertainty of ambitious targets.
The share price fell from an intraday high of KRW 34,500 on the first day to KRW 21,050 as of 18:14 KST, and market capitalization of KRW 238.9 billion compares with KRW 173.7 billion at the offer price. Second-half results, the revenue split by customer and progress on capacity additions will give clearer evidence.
